Firstly make the filling, add all of the ingredients to a bowl and mix well. Place in the fridge for 20 minutes and then form into 8 small balls on a tray. Place balls in the freezer while you continue to make the Mochi.
Add rice flour, sugar and salt into a large bowl and mix well, add hot coconut milk and stir until liquid has been fully absorbed. Cover with cling film and microwave for 3 minutes. Stir mixture well, re-cover with cling film and microwave again for a further 1 and half minutes.
With a large wooden spoon mix the mixture together for at least 8/10 minutes until it is stretchy. This will make the Mochi nice and chewy.
Divide mixture into 8 pieces. Lightly cover your hands with cornflour, take a piece of the mixture and roll into a ball in the palm of your hand, now flatten out into a disc and place filling into the centre and gather ends together to reform a ball. Sprinkle with desiccated coconut and serve.
